  • Patent number: 10310537
    Abstract: A sub-nW voltage reference is presented that provides inherently low process variation and enables trim-free operation for low-dropout regulators and other applications in nW microsystems. Sixty chips from three different wafers in 180 nm CMOS are measured, showing an untrimmed within-wafer ?/? of 0.26% and wafer-to-wafer ?/? of 1.9%. Measurement results also show a temperature coefficient of 48-124 ppm/° C. from ?40° C. to 85° C. Outputting a 0.986V reference voltage, the reference operates down to 1.2V and consumes 114 pW at 25° C.
